Step-by-step explanation:
-10 or -20 satisfies the equation.
But when you substitute 10 in:
30-40<-50+8
-10<-42(wrong)
it's wrong
Answer:
Student-A:
mile/min
Student-B:
mile/min
Student-C:
mile/min
Step-by-step explanation:
Student-A:
she can run 2/3 mile in six minutes
so,
total distance is miles
total time =6 min
we can use formula
speed=(total distance)/(total time)
mile/min
Student-B:
she can run 1/2 mile in 4 minutes
so,
total distance is miles
total time =4 min
we can use formula
speed=(total distance)/(total time)
mile/min
Student-C:
she can run 4/5 mile in 8 minutes
so,
total distance is miles
total time =8 min
we can use formula
speed=(total distance)/(total time)
mile/min
Answer:
50 yards because of the roundness of the table
The relation maps a unique output value to each input value. It is a function.
Answer:
y = 1/2x + 1
In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.
-2 ⇒ 1/2
Next, we need to substitute the information given into the point-slope formula.
The point-slope formula is:
y - y₁ = m(x - x₁)
y - 1 = 1/2(x - 0)
y - 1 = 1/2x
y = 1/2x + 1
Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
